Worker major. — Length 7.5-9 mm. 



Resemliling the var. decipiens in color but decidedly larger. Head, 

 thorax, petiole, antennje and legs rich yellowish red ; gaster black, extreme 

 base of first segment and sometimes the venter deep red ; mandibles sometimes 

 red, teeth black, anterior margins of cheeks and clypeus somewhat infuscated. 

 Antennal funiculi red throughout. 



Worker minor. — Length 4-6 mm. 



Colored like the worker major but the lighter portions are often more 

 yellowish. 



Female. — Length 9.5-10.5 mm. 



Colored like the worker major ; margin of the scutellum and sometimes 

 also the metanotum blackish. Wings yellowish, with yellow veins and stigma, 



Male.- — Length 6.5-7 vara. 



Closely resembling the males of the preceding varieties ; gastric segments 

 narrowly yellowish at the base ; antennal funiculi brown ; articulations of the 

 legs yellowish : wings as in the female. 



My series of specimens represents the following localities : 

 Texas: Austin, New Braunfels, Marble-Falls, and Granite Mt. in 

 woody galls of Holcaspis cinerosa on Qucrciis virginiana; also in 

 logs and branches of the same tree (Wheeler) ; Barksdale (Brown) ; 

 Victoria, in twigs of willow (W. D. Hunter and J- D- Mitchell) ; 

 Langtry (Wheeler); Kerrville (F. C, Pratt), Llano (J. C. Craw- 

 ford), Tyler (R. C. Howell), Calvert (C. R. Jones). 

 Arizona: Tucson ■ (Wheeler). 

 Louisiana: Keatchie (W. Newell). 



Florida: Miami (Wheeler); Sanford (Jerome Schmitt). 

 I regard this form as a distinct subspecies on account of its large 

 size and the constancy of its coloration. This constancy is the more 

 noteworthy because it is one of the most abundant ants in portions of 

 the Southern States. 



7. C. fallax rasilis var. pavidus, new variety. 

 Worker major. — Length 6-7 mm. 



Coloration of head, thorax, petiole and appendages as in rasilis but the 

 base of the gaster clay yellow. In most specimens the first and second seg- 

 ments are of this color throughout but in others only the base of the first seg- 

 ment is yellow and the remainder of the gaster is black. Antennal funiculi 

 scarcely infuscated towards their tips. 

 Worker minor. — Length 4-5 mm. 



Colored like the major worker and exhibiting the same variations. 

 Female. — Length 8.5 mm. 



Colored like the major worker; thorax yellowish-red throughout, only the 

 border of the scutellum being somewhat infuscated. In one specimen the
